Hi Scott B, Check section 6.12 in the APL Function Manual: http://support.automation.siemens.com/WW/view/en/80539207 Digital feedback signals for the "Open" and "Closed" positions are formed from the position feedback: ● Feedback for "Open" position: Rbk ≥ PosDiOpen ● Feedback for "Closed" position: Rbk ≤ PosDiClose The key here is subtracting the valve output from 100% before connecting the channel driver. The same principle can be used for formulating the feedback signals. Normally this should be achievablevia a Feature Bit selection and I did not see one.Am I missing it? Regards |
